What Does “All Applicable Airworthiness Requirements” Include? 14 CFR Part 43.15 requires mechanics to verify that each aircraft meets all applicable airworthiness requirements when conducting inspections (annual, 100 hr, etc.). What does this include?

Some items may be Airframe, Engine and Propeller Total Time, Status of Life Limited Parts, Time since Overhaul, Current Inspection Status, Status of Airworthiness Directives, Copies of 337 Forms, Altimeter, Transponder, and ELT inspections.

You should also confirm that maintenance previously performed, especially maintenance that was not recorded in the maintenance records (or is no longer in the maintenance records), is inspected, and that inoperable equipment is repaired, replaced or properly deferred. These items can be found in the regulations and in the Inspection Authorization Knowledge Test Guide (FAA-G-8082-11C).
